ata: sata_mv: Fix PCI device ID table declaration compilation warning

[ Upstream commit 3137b83a ]

Building with W=1 shows a warning for an unused variable when CONFIG_PCI
is diabled:

drivers/ata/sata_mv.c:790:35: error: unused variable 'mv_pci_tbl' [-Werror,-Wunused-const-variable]
static const struct pci_device_id mv_pci_tbl[] = {

Move the table into the same block that containsn the pci_driver
definition.

Fixes: 7bb3c529
